Williams Winter Jam 2020 was held during the final week of the Winter Study course Video Game Appreciation 1972-1992. Students ranged from first-time programmers to seniors concentrating in Computer Science. All games were programmed in Lua using the Pico-8 fantasy console. Thirty students participated and submitted 23 games. Participants voted for their favorite game and the Judge's Picks were selected by the instructor. Each game is playable in a web browser, and can be found on the Pico-8 forums using the #wwj20 tag, or by clicking its thumbnail image below.
